What to do: Another way to fight a craving is to brush your teeth instead of eating. Feeling the menthol of the toothpaste in your mouth, your brain gets a signal that the meal is over.

What happened: Exactly what was promised, as strange as that was. Even if there was a pang of hunger, going for lunch wasn’t on my mind for another hour or two. That is because, for me, brushing my teeth is associated with the end of a day and going to sleep.
